PERFORMANCE ASSESSMENTS INSIGHTS ON THE USE OF CEMENTS IN WASTE MANAGEMENT

November 7, 2010
Author(s)
David W. Esh, Jacob Philip, Kenneth A. Snyder
The use of cementitious materials has been proposed in a variety of waste management systems because these materials can have a variety of desirable performance characteristics: hydraulic isolation, chemical isolation, structural stability. Cementitious

A Review of Building Evacuation Models, 2nd Edition

November 1, 2010
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Bryan L. Hoskins
Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-of-the-envelope (hand) calculations to assess life safety, and in

Technical Study of the Sofa Super Store Fire- South Carolina, June 18, 2007 Volume I ***DRAFT FOR PUBLIC COMMENT*** (for final version, see NIST SP 1118, March 2011)

Author(s)
Nelson P. Bryner, Anthony D. Putorti Jr., Stephen P. Fuss, Bryan W. Klein
A fire occurred on the evening of June 18, 2007, in the Sofa Super Store in Charleston, SC. NIST analyzed the fire ground, consulted with other experts, and performed computer simulations of fire growth alternatives. Based on these analyses, the following

Fire Effluent Component Yields from Room-scale Fire Tests

October 1, 2010
Author(s)
Richard G. Gann, Jason D. Averill, Erik L. Johnsson, Marc R. Nyden, Richard D. Peacock
Estimation of the time available for escape (ASET) in the event of a fire is a principal component in fire hazard or risk assessment. Valid data on the yields of toxic smoke components from bench-scale apparatus is essential to accurate ASET calculations

Methodology for Calculating Construction Industry Supply Chain Statistics

September 30, 2010
Author(s)
Douglas S. Thomas
Data from the Economic Census provides detailed statistics on the construction industry; however, the data is only gathered every five years. The Bureau of Labor Statistics provides statistics on the construction industry on an annual basis, but these

FIRE PATTERN REPEATABILITY: A LABORATORY STUDY ON GYPSUM WALLBOARD

September 1, 2010
Author(s)
Daniel M. Madrzykowski, Charles Fleischmann
In 2009, the National Research Council (U.S) published a report identifying the research needs of the forensic science community. In the field of fire investigation, one of the specific needs identified was research on the natural variability of burn

Building Occupant Egress Data

August 27, 2010
Author(s)
Richard D. Peacock, Erica D. Kuligowski
Data on people movement on stairs were collected from 9 office and residential building evacuations in the United States. The buildings involved in this study range from 6 stories to 62 stories in height. The data were collected by positioning video

CHRISTIFIRE (Cable Heat Release, Ignition, and Spread in Tray Installations during FIRE) is a U.S. Nuclear Regulatory Commission Office of Research program to quantify the mass and energy released from burning electrical cables. This type of quantitative

Infiltration of Outdoor Ultrafine Particles into a Test House

August 2, 2010
Author(s)
Dong H. Rim, Lance L. Wallace, Andrew K. Persily
Ultrafine particles (UFP) have been related to adverse human health effects such as respiratory and cardiovascular mortality. However, human exposure to particles of outdoor origin is heavily dependent on their infiltration into homes, where most people
